摘要: A fluid treatment plant has a filter module including at least a first filter and a second filter connected in series and connectable to a supply of fluid. A pump is fluidly connected to the filter module and a controller with a fluid quality sensor is connected to detect a quality of the fluid between the first filter and the second filter. A filter module detector is connected to the controller configured to uniquely detect a filter module connected to the pump, and the controller is controls the pump responsively to a signal from the fluid quality sensor and the module detector. The controller is configured to continue pumping based on output of the quality sensor and/or based on output from the filter module detector.

摘要: Features for protecting against leaks in a fluid circuit are disclosed. In an embodiment, a first indicator of a leak is used to trigger confirmation by blood flow reversal and air detection in the blood circuit. A method for performing a blood treatment includes, at blood treatment machine, pumping blood to a patient through a first blood line. Further, at a controller of the blood treatment machine, a first signal is received, indicating a probability of a leak in the first blood line. Responsively to the first signal, the controller commands a leak verification operation and receives a second signal indicating whether a leak in the first blood line is verified. Further, a leak indicating signal is generated if the second signal indicates a leak is verified.

摘要: The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. A blood treatment system treats blood with multiple fluids and performs fluid balancing on a patient's blood compartment. Multiple streams influence the patient temperature but only a subset of the fluids are dynamically temperature regulated. The system regulates a temperature of the flow, for example, of dialysate in order to regulate the return temperature of blood, in such a way that the temperature effect of the multiple streams is compensated.

摘要: A treatment device system includes a treatment machine for generating a custom dialysis solution and including at least one fluid conveyor, the treatment machine having a controller, the controller having a first memory, configured to produce the custom dialysis solution by causing the at least one fluid conveyor to mix purified water and at least one concentrate. The system also includes a user interface and a water purifier in fluid communication with and providing the purified water to the treatment machine, the water purifier including an internal central controller, the internal central controller having a second memory, to control preparation of the purified water. A server is communicatively coupled with the treatment machine and a control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier.

摘要: Methods, systems, and devices are disclosed, embodiments of which provide single pass dialysis to remove water and uremic toxins is performed simultaneously with the albumin dialysis therapy by passing the albumin solution through a dialysis filter which dialyses it before the solution is returned to the cycler. In embodiments, the single pass dialysis stage is upstream of the albumin filtering stage.

摘要: A method of performing a peritoneal dialysis treatment includes connecting a disposable unit to a source of water. The disposable unit includes at least a first container holding a sterile concentrate containing an osmotic agent, a second container holding a sterile concentrate containing electrolytes, an empty sterile mixing container, and a tubing set with a pre-attached peritoneal fill/drain line. The method also includes receiving a prescription command by a controller, indicating at least the fill volume and desired final concentration of the osmotic agent to be used for a current fill cycle under said treatment, and pumping a quantity of the concentrated osmotic agent that is at least sufficient to achieve the desired final concentration into the mixing container. The contest of the mixing container are mixed, further diluted or concentrated, and then flowed to a patient.

摘要: A disposable fluid circuit used in a medical device that performs peritoneal dialysis includes a peritoneal dialysis tubing set that has a connection tube with a connector for a peritoneal catheter at a distal end and a connector configured to connect to a peritoneal cycler at a proximal end. The circuit also includes a pressure pod at the distal end, the pressure pod being of the type that has a flow chamber for carrying a liquid and an air chamber separated from the flow chamber by a diaphragm and an air port in fluid communication with the air chamber. The flow chamber is connected in-line with a lumen of the connection tube and a length of tubing runs from the air-port along the length of the connection tube with a connector at the proximal end configured to connect to a pressure transducer.

摘要: Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed through a first filtration step which is effective for creating purified water and a pair of ultrafilters placed at the outlet. The ultrafilters are separated by an intervening flow path to prevent grow-through from the outlet end upstream. In embodiments, a recirculation path with an air removing filter helps to eliminate air from the ultimate product water.
